The hand bent aluminium chassis was replaced by the steel machined chassis, making the amps much more robust and road proof.

In exchange for the necessary funding (to build this new factory) Rose Morris acquired the exclusive worldwide rights to distribute Marshall amps for the next 15 years. The first combos (models 1961 & 1962) appeared halfway this year.ĭesperate to build a factory large enough to meet demand, Jim Marshall made a deal with the Rose Morris company. The speaker cabinets were closed 4×12″ Celestion loaded cabinets. These amps were built as heads (or tops) separated from the speaker cabinets. These amps were more or less a copy of the Fender 1959 Tweed Bassman. The very first Marshall amps that saw the light of day were called the JTM45 amps. Little did they know then that they were at the threshold of a rock ‘n roll revolution… 1962

Their first amps were very heavily “inspired” on the 1959 Fender Tweed 4×10″ Bassman. He did this together with Ken Bran and aided by the technical engineer Dudley Craven. Jim Marshall started building amps in 1962. Sadly, Jim Marshall, the Father of Loud, passed away on april 5th 2012.
